A method for the manufacture of a stocking in such a manner is described in the U. S. application Ser. No. 270,669 of applicant filed April `28, 1939 and entitled A method o f "'making y stockings.

The main feature of this earlier application l consists in this that for the manufacture of the heel parts the loops of each second rowy of heel loops are alternately transferred outwardly for one needle except the loops hanging on the innermost two or three needles and that the inner limit of the path or stroke of the heel thread carriers, is, each time after four rows of loops have been formed, reduced for the distance of two needles from one another which needles are placed in an inoperative position.

For closing openings produced by transferring outwardly according to one modification the loop of thenot .transferred second row of loops of each group of heel loops, consisting of four `row of heel loops.

lFor the purpose of the invention it is of noimportance whatever in which manner the rows of .loops and hanging on the innermost needle in the following row of loops to be transy ferred outwardly, is not pressed in the following row and on transfer of the third row loops is transferred as double loop together with the noose formed on this needle;

Now., it has been provedthat this method of closing openings caused by outwardly transferring is not satisfactory in so far as the double loops have larger distance from each other, whereby, due to the different noose formations, an irregular and undesired loop diagram results.

To prevent this drawback, the loop of each not transferred row of heel loops which hangs on the innermost needle of the following row of loops to be transferred outwardly is not pressed in the following row of loops and on transfer outwardly of this row of loopsis transferred as double loop --together with-the noose formed on this needle.

- Hereby a. continued trace of double loops as -well-.as a uniform noose formation results for closing openings caused by transferring out- 'wardly. A further feature of the present invention consists this that, for the purpose of obneedle, forming the inner limit of the path or stroke of the heel parts, is treated, i. e. in which manner this needle is pressed or not pressed.

In the accompanying drawing a loop diagram formed by one mode of carrying out the operation according to the invention is shown by way of example. t

According to the example shown, the loop hanging on the needle 3 of the last row a. of the leg is not pressed in the following row. In the row following manufacture of the heel parts in which the first row b of heel loops is formed on the needles B-l only the loops, with the exception of the loops hanging on the two innermost needles l and 2, are outwardly transferredfo'r the distance of one needle. Hereby the loop of the row a hanging on the needle 3 is outwardly transferred to the' needle 4 together with the noose of the rst row b of heel loops formed upon the needle 3 so that now loops hang on the needles i, 2 and 4 9.

In the following. second row c of heel loops which is not transferred the heel thread carrier performs, starting from the same inner limit of the stroke or path (needle l), a stroke or path which is larger about the distance of two needles.

Due to the fact that the last added marginal loop does not find a counterploop to which it could be connected this marginal loop disappears again by being pressed oi.

In the following third row d of heel loops in which the loop hanging on the needle t of the row c is not pressed and in which the heel thread carrier performs the same path orstroke as in the row of loopsc the loops are again transferred outwardly about the distance of one needle. In this row also the marginal loop disappears because it is pressed off without finding a counter- The marginal loop of the following fourth row e of heel loops which again is not transferred and in which the heel thread carrier performs the same path or stroke as in the rows c and d of the loops, now is connected to the transferred marginal loops of the row d. In the next row the loop hanging on the needle 5 isnot pressed. The outer limit in each heel part is increased by the distance of two needles.

In the following row of loopsthe inner limit of the path or stroke of the heel thread carrier is displaced outwardly about the distance of two needles. The following rows are produced in the same manner as the rows b-e of the heel loops.

According to the example shown, the needle l,

forming the inner limit of the path or stroke of the heel parts, is not pressed in the rows c and e. Y

only, or be treated in any desired other manner.

` Moreover, the outward transfer of the double Of course, the needle I could also be pressed v in each row or be not pressed in the rows d and e loops could also be started in the row d.

What I claim is:

A method for the manufacture of a stocking in a single operation on a flat knitting machine in which the heel parts are formed while the loops of the middle portion are placed in suspense with outer groups of loops in said heel parts being transferred outwardly in alternate courses only, which comprises retaining in intervening courses the loops on the innermost needles of the groups of needles from which loops are to be transferred in said alternate courses to form tuck or double loops whereby the innermost loop in each group of transferred loops is a double loop. v
